Flock size and breeding success in flamingos

Using data on flocks of flamingos in Britain and Ireland, the relationship between flock size and breeding in captive flamingos was examined. Breeding flamingo flocks were significantly larger than nonbreeding flocks and larger flocks bred more frequently than smaller flocks. All Chilean flocks containing more than 40 birds have bred successfully; however, one flock of only 4 Chilean Flamingos has reared at least one chick. All Caribbean flocks over 20 birds have successfully reared a chick, yet the smallest flock to rear a chick was one of 14 birds. © 1992 Wiley‐Liss Inc.
